  This header defines macros which enable compile-time program

  instrumentation. These macros work for both C and C++. Enclose the entire

  statement to be debugged within the DBG() macro *and* put the semicolon

  after the macro. (e.g., DBG(cerr << "Bad program" << endl); ). Statements

  should not span lines unless they include `\'s to escape the newlines.
